I estimate that TST, all by itself, nearly doubles Firefox's memory footprint. Sidebery freed up 5-10G of memory for me by comparison (yes, way too many tabs...). TST should *not* be a recommended extension. Latest update of TST leaks memory *very badly* and crashes, taking other Firefox extensions and other desktop programs down with it when the OS starts killing things to free up memory. Sidebery is *much* more responsive & performant with a very large number of tabs. This alone will remove a huge amount of friction in reducing the number of open tabs. No more waiting for TST to catch up. Switching to Sidebery was no problem: all nesting retained. Disable TST. Install Sidebery and verify ok. Remove TST. Done.

after using ~one mouth going between tabs is lagging so it`s impossible to use

Updating to Firefox 107 breaks autohide tabs feature - it won't work. Very useful but broken addon.

What the smeg ?! It opens the bookmarks sidebar !? How hideous is that ! I was expecting the tabs to cascade from their default position, you know, as actual tabs ! This is mental ! Useless.

There's some memory leak issue with this extension. Keeps using up all of my system's 16 GB RAM.

в текущих реалиях, ввиду того на сколько развилась работа с вкладками в лисе, расширение просто дублирует то что уже имеется и не является необходимым если вы не хотите видеть свои же вкладки по всему браузеру словно рекламу - просто повсюду...3 панели управления вкладками, не чересчурли

Poor optimization and doesn't even remove the top bar so it's making things worse.

I expect that tabs are grouped automatically by root domain search on top in text box by words.

Jan 30, ver 3.9.21, all tabs disappear. It so confuse.
